DETAILED DESCRIPTION OF THE INVENTION

Embodiments of the invention include systems and methods of attaching toys or other items to child care equipment, and include pieces of child care equipment having features for attaching toys or other items.

In some embodiments, the piece of child care equipment is configured to include a track, such as a rod, and a sliding member that moves along the track. The sliding member is configured so that one or more toys or other items can be easily and releasably attached to it. Toys or other attached items can be interchanged and moved to different locations as desired. For example, the track may be suspended above a baby in a play gym, and toys hanging from the track may be moved to be within the baby's reach. The track may also be part of another kind of equipment, such as a pad or pillow, and attached toys or other items can be moved to a location where the child is lying. Other kinds of attachments may also be provided. The track may be completely embedded within the piece of equipment, such as within a fabric sleeve, with the clip sliding over a fabric sleeve. Alternatively, the track may be coupled to the equipment such that the track remains exposed. In this way, the clip slides directly over the track.

For example, FIG. 1A shows an infant play gym 100 in accordance with embodiments of the invention. Play gym 100 comprises a base pad 101, and a canopy 102. In one mode of use, play gym 100 is placed on a floor. Base pad 101 includes a padded center portion 101 a and a padded peripheral portion 101 b that forms an outer boundary for holding the baby. A seam is formed between portions 101 a and 101 b where the fabric from each of the portions is joined together. One convenient way to construct base pad 101 is by placing a batting on the fabric, then sewing the fabric together to form the various seams. The stitching between center portion 101 a and peripheral portion 101 b serves to limit the amount of shifting of the fill material. An infant is placed on base pad 101, and may interact with various toys or other items such as item 103 suspended from canopy 102 or attached to base pad 101. Play gym 100 thus provides a safe, comfortable, and convenient place for the baby to spend time, and also provides stimulation for the baby's entertainment and development. Play gym 100 may be especially useful for the care of infants who have not yet begun to crawl. Having items attached to play gym 100 keeps the baby's toys in a contained area and within the baby's reach.

Base pad 101 may be, for example, made of a soft cloth or fabric, and may be filled with padding such as foam or fiberfill padding or batting. Base pad 101 is preferably of a size suitable for holding a baby. For example, base pad 101 may be about 30 to 36 inches across, but other larger or smaller sizes may be used. Base pad 101 may be of any suitable shape, including round, oval, oblong, rectangular, or another shape.

Base pad 101 includes three attachment members 104 a-c affixed to an edge portion of base pad 101. One of skill in the art will recognize that more attachment members may be provided. Attachment members 104 a-c may be, for example, fabric-covered foam or fiberfill material in a ball shape, or another suitable shape. While attachment members 104 a-c are preferably compressible, substantially rigid shapes could be used as well, for example plastic balls. Each of attachment members 104 a-c may be affixed to base pad 101 by sewing a portion of the covering of the respective attachment member into an edge seam of base pad 101, by sewing a tether to both the attachment member and base pad 101, or by any other suitable means.

Canopy 102 is configured to arch over base pad 101, standing on three legs 105 a-c, forming an arched support frame. Canopy 102 may reach a height of , for example, 12-24 inches over base pad 101, and may be used to hang toys or other items 103 within reach of a baby placed in play gym 100. One of skill in the art will recognize that more legs and other dimensions could be used. Canopy 102 comprises a surface sheet 106, which may be, for example, a fabric or plastic sheet, and may be of a single thickness, or comprise multiple thicknesses of one or more materials. Surface sheet 106 may be made of multiple pieces integrated together, and the pieces need not be of the same materials. Canopy 102 also includes at least two semi-rigid rods 107 a and 107 b embedded within canopy 102. Semi-rigid rods 107 a and 107 b may be, for example, made of a plastic, metal, or composite material, and may be round or another shape in cross section. Semi-rigid rods 107 a and 107 b are preferably stiff enough to remain substantially straight when unstressed, to lightly resist bending, and to regain substantial straightness when any bending force is removed. In one example embodiment, rods 107 a and 107 b are each about 28 inches long and about ¼ inch in diameter, and are made of unreinforced plastic. Other appropriate sizes may be used.

First ends of both rods 107 a and 107 b follow a first leg 105 a of canopy 102 to its connection with base pad 101. Preferably, rods 107 a and 107 b are embedded within edges of surface sheet 106, but other placements may be used. A second end of first rod 107 a also follows second leg 105 b to its connection with base pad 101, and a second end of second rod 107 b follows third leg 105 c to its connection with base pad 101. Rods 107 a and 107 b thus support canopy 102 by virtue of their stiffness, similar to the way a tent may be supported by tent poles.

As described in greater detail hereinafter with reference to FIG. 3A, a clip 301 is slidingly engaged with rod 107 a. Clip 301 may slide anywhere along rod 170 a to adjust the position of one or more toys that are coupled to clip 301. This provides a convenient way for a caregiver to adjust the location of a toy relative to a child. For example, when removing the child from base pad 101, when changing a diaper or cleaning the baby, the caregiver can simply slide clip 301 along rod 107 a to afford better access into the interior of the tent. To keep the child entertained, slip 301 may be slid such that the toy hangs over the arched support. Although shown attached to rod 107 a, it will be appreciated that clip 301 may be coupled to any of the rods. Moreover, multiple clips could be attached to a single rod. Also, multiple toys may be chained together, such as toys 122 and 124 of FIG. 1A, to increase the length of the toy and provide a different arrangement for the toys that are suspended from base pad 101.

Base pad 101 may also include one or more tracks 130 that may be coupled anywhere along a top or side of base pad 101. Track 130 is a semi-rigid rod that may function similar to the rod 107 a in supporting one or more clips 350 as described in greater detail hereinafter with reference to FIGS. 3C and 3D. As further illustrated in FIG. 1C, track 130 comprises a semi-rigid rod that is coupled to base pad 101 by a fabric sleeve 132. More specifically, sleeve 132 may comprise a fabric strip that has its lengthwise ends sewn into a seam 133 in base pad 101 to form a tube. Seam 133 is the seam that is formed when connecting portions 101 a and 101 b. The rod is slid through sleeve 132 and then the ends 136 and 138 of sleeve 134 are sewn down and incorporated into the seam. Prior to sewing the ends into the seam, clip 350 is inserted over the fabric sleeve. In the way, clip 350 will not detach from track 130. As another option, the ends of the rod may be held in pockets to secure the rod to base pad 101. In this way, a fabric sleeve would not be needed.

One or more toys 126 may be coupled to clip 350 in a manner similar to that described in connection with other embodiments. This allows items, such as toys to be removably coupled with base pad 101. Further, the location of the items can easily be adjusted by sliding them along track 130 using clip 350. For example, a toy can be moved to a mid portion of base pad 101 to provide easy access to the toy by the child. However, when the child needs to be removed from base pad 101, clip 350 may be slid to one side to move the toy. As another example, clip 350 may be slid along track 130 to place the toy in a different location to thereby provide a different environment within the play structure.

The fabric used to form fabric sleeve 132 should be durable because of friction caused by the slider clip when moving over the rod. The fabric should be sufficiently durable so that the rod will not break through the fabric over time. Preferable fabrics include nylon fabrics. An especially good fabric is a denier nylon with or without a polyurethane coating.

FIG. 1B shows canopy 102 separated from the rest of play gym 100. Canopy attachment loops 108 a-c are placed at the lower ends of legs 105 a-c. Loops 108 a-c are configured to engage the attachment members 104 a-c to attach canopy 102 to base pad 101. To make the attachment, each attachment member is passed through its respective loop. If attachment members 104 a-c are compressible, each attachment member may be compressed to pass through its corresponding loop and then allowed to re-expand. Canopy attachment loops 108 a-c may also be stretchable, so that when the loops are unstretched, the loops are smaller than the attachment members. This arrangement may help ensure a secure attachment of canopy 102 to base pad 101, but also allow for easy disassembly of play gym 100. As another option, loops 108 a-c may each comprise two straps with ends having a hook and loop fastener material. In this way, the two straps may be wrapped about the attachment members 104 a-c and then secured to each other about their respective ends.

Play gym 100 may comprise one or more openings for attaching items 103 to play gym 100. For example, surface sheet 106 may include spaced apart holes 109, which may be reinforced by stitching around the perimeter of the hole or by other means. In another example, base pad 101 or canopy 102 may include loops such as item attachment loops 110 shown in FIG. 1. These holes and loops may be used to attach various toys, such as, for example, the toy in FIG. 2. However, the holes and loops can also be used with traditional toy links, also referred to as “C” clips or “C” links, to which various items may be attached.

FIG. 2 shows an example item 103 that may be attached to play gym 100. In this example, item 103 is a ball configured to attach to play gym 100, but many different kinds of items may be configured to attach to play gym 100, including such items as a toy, a block, a pyramid or other geometric shape, a doll, a teething ring, an item comprising a mirror, a toy shaped like an animal or insect, a toy shaped like a plant or flower, or another suitable item. Preferably, items attached to play gym 100 are selected to be entertaining and stimulating to an infant placed in play gym 100.

As is shown in FIG. 2, item 103 includes a main body 201 and a compressible member 202 connected to the main body 201. In this example, compressible member 202 is connected through tether 203, but other connection arrangements may be used. Compressible member 202 may have any suitable shape, such as a ball shape, a block shape, a pyramid shape or other geometric shape, a button shape, a leaf or flower shape, an animal shape, a shape reminiscent of wings, or another shape. The shapes may or may not incorporate sound, light or vibration features. Compressible member 202 is preferably somewhat larger in its uncompressed state than holes 109 or item attachment loops 110. Item 103 may then be attached to play gym 100 by squeezing compressible member 202 through one of holes 109 or item attachment loops 110 and allowing compressible member 202 to re-expand, providing a secure but easily removable connection. This attachment system has the additional advantage that the materials involved may be soft and pliable and all of the parts may be relatively large, resulting in a safe environment for the infant.

FIG. 3 a illustrates another embodiment of an attachment of an item 302 to play gym 100. In this embodiment, clip 301 is slidingly engaged with rod 107 a. One or more clips such as clip 301 may be engaged with any or all rods of canopy 102. Preferably, rod 107 a is embedded in play gym 100 so that it is accessible for engagement with clip 301. For example, rod 107 a may be embedded by wrapping rod 107 a in a portion of surface sheet 106. In that configuration, rod 107 a may be thought of as residing in a tubular pocket sewn into surface sheet 106. Not all of the rod need be wrapped or embedded. Even if part of a rod is wrapped, some of the rod may be left exposed. In some embodiments, the portion of surface sheet 106 wrapping rod 107 a may be made of a woven nylon or other durable fabric, to provide a suitable amount of friction to clip 301, and to resist wear.

FIG. 3 b illustrates clip 301 in isolation. Clip 301 is generally toroidal, but need not be perfectly toroidal. A slotted passage 303 is provided at one side of clip 301. Slotted passage 303 is configured to slidingly engage a rod such as rod 107 a. The rod and slotted passage may be any size, so long as passage 303 is sized so that clip 301 is easily slid along the rod, but will maintain its position on the rod when left at rest. This kind of sliding fit may be facilitated by the natural compliance of a portion of surface sheet 106 that may be wrapped around the rod, and by the split configuration of passage 303. Clip 301 is preferably substantially rigid so that it is not reasonably removable from the rod without sliding clip 301 past an end of the rod.

Once clip 301 is engaged with rod 107 a (or another rod) the fabric or other material wrapping rod 107 a may engage with slot 304 of passage 303, and limit the rotation of clip 301 around rod 107 a. Hole 305 in clip 301 provides an opening configured for attaching items to play gym 100. For example, compressible member 306 of item 302 may be passed through hole 305 to hang item 302 from canopy 102. Multiple clips 301 may be provided on play gym 100, and one or more clips may be provided on any or all semi-rigid rods used to support a canopy. Any or all clips 301 mounted on canopy 102 may be easily moved to adjust the positions of items such as item 302 attached to canopy 102 using clips 301.

It will be appreciated that many variations are possible in the configurations of the items to be attached to a piece of child care equipment such as play gym 100.

For example, referring again to FIG. 1, item 111 may comprise a mirror surface (which may be surrounded by suitable padding) to allow the child to see a reflection of himself or herself. Item 111 also illustrates another variation. Item 111 includes two compressible members 112 and 113, which are passed through two of item attachment loops 110, to further constrain the position of item 111. In another example, item 302 shown in FIG. 3A has a main body in the shape of an animal. Other items may have main bodies shaped like insects, plants, flowers, geometric shapes, or other objects that may entertain or stimulate the child.

In some embodiments, an item attached to a piece of child care equipment may generate sound. For example, a ball or other item may be filled with a material that makes a crackling sound when the ball is squeezed, encouraging the child to interact with the item. An attached item could include an electronic sound generating device that plays music, animal sounds, tells a story, or generates some other kind of sound when the item is squeezed, caused to move, or otherwise activated. In addition, an item may also incorporate a light feature or a vibration feature which can be activated by movement or a switch, also encouraging the child to interact with the item.

FIGS. 3C and 3D illustrate clip 350 of FIG. 1A in greater detail. Clip 350 comprises a clip body 352 that is generally toroidal in geometry. Clip body 352 has a slot 354 leading to a passage 356 through which the rod will slide. Slot 354 is wide enough to prevent the fabric sleeve to slide through it. Passage 356 is sized to be just large enough so that it can smoothly slide over the rod and fabric sleeve. If passage 356 is too large, clip 350 will be too loose and will not easily slide, and may be able to separate from the rod. Conversely, if it is too small, then it will bind against the sleeve and/or rod making movement difficult. Thus, the rod should be small enough that it can be wrapped in the nylon fabric forming the sleeve and still have the clip slide, but not so small that the clip snaps off the rod and presents a safety hazard. The passage in clip 301 may be sized in a similar manner. Clip 350 also defines a central opening 358 where a compressible member of a toy may be placed similar to other embodiments described herein.

Another feature of clip 350 is that slot 354 is generally perpendicular to the clip body, while with clip 301 the slot 304 is parallel to the clip body. This permits clip 350 to be generally parallel to the base 101 as illustrated in FIG. 1A so that it does not stick up and interfere with the baby's play. With clip 301, the clip body is generally aligned with the fabric on the arched support. While the clip body does extend from the rod, this does not interfere with the baby's play and also allows the toy to more easily hang from the arched support. In some cases, clips may be constructed where the slot is at different angles relative to the clip body, such as 15 degrees, 30 degrees, 45 degrees, 60 degrees and the like, to permit the clip body to be at different angles relative to the adjacent fabric or base layer.

Many variations are also possible in the shapes of the compressible members used to attach items to the child care equipment. For example, compressible member 202 shown in FIG. 2 may be reminiscent of leaves, animal ears, or wings. Compressible member 306 shown in FIG. 3A is in a simple ball shape. Other possible shapes include a flattened ball or button shape, other geometric shapes, leaf and flower shapes or animal shapes.

FIG. 4 shows another example item 401 attached through a clip 301 engaged with rod 107 a. In this example, item 401 includes a button-shaped compressible member 402 engaged with clip 301. The main body of item 401 is generally toroidal or donut shaped having an opening 403. A second item 404 is suspended from opening 403 in item 401. In this example, second item 404 includes a teething ring, and also includes a compressible member 405 in a shape reminiscent of leaves.

Attachment systems and methods according to embodiments of the invention may be used with a variety of child care equipment. Play gym 100 shown in FIG. 1A is but one example. Other kinds of equipment that may embody the invention include, without limitation, a play yard, a playpen, a swing, a baby bouncer, a shopping cart liner, a stroller, a car seat, a booster seat, a high chair, a play pad, a changing pad and a changing pad cover.

In one example, FIG. 5 shows a play yard 500 in accordance with embodiments of the invention. A play yard is a device similar to a traditional playpen, and is designed to provide a safe and constrained space for a child to spend time. A play yard may be placed, for example, in a corner of a room, or even outdoors when it is desired that the child accompany a group on a picnic or other outing. Play yard 500 includes features for attaching toys or other items. For example, play yard 500 includes a dome 501, which may include holes 502 for attaching items as previously described. An edge of dome 501 may include an embedded semi-rigid rod 503 and a clip 301 slidingly engaged with rod 503 for attaching items. Other portions of play yard 500 may also include openings or rods. For example, a wall or side 504 of play yard 500 may include holes 502, an embedded semi-rigid rod 505, or both; or the bottom of the play yard may include an embedded semi-rigid rod. Other examples of play yards or other play structures that may include such attachment systems are described in U.S. Pat. No. 7,290,303, and Published U.S. Application No. 2007/0271703 and 2002/0042953, incorporated herein by reference.

In another example, FIG. 6 shows a swing 600 in accordance with embodiments of the invention. Example swing 600 includes an arched support frame 601 that includes holes 602 in a surface sheet and an embedded semi-rigid rod 603 for attaching items, for example using clip 301. Swing 600 may be used, for example, to provide a place for a baby to relax, with the swinging motion providing a comfort and enjoyment for the baby. The items suspended from arched support frame 601 provide additional entertainment and stimulation.

FIG. 7 shows a bouncer 700 in accordance with embodiments of the invention. A bouncer is a device used in a manner similar to a swing, but provides a bouncing motion rather than a swinging motion. Bouncer 700 also includes an arched support frame 701 having holes 702 in a surface sheet and an embedded semi-rigid rod 703, for mounting items using a clip 301.

FIG. 8 shows a shopping cart liner 800 in accordance with embodiments of the invention. Shopping cart liner 800 is configured to nest in the child seat portion of a shopping cart to provide a clean liner over unsanitary surfaces. Liner 800 also provides protective soft surfaces for a child to encounter, rather than the hard, cold materials of which the shopping cart itself is usually made. Similar liners may be constructed for strollers, child car seats, high chairs, booster chairs, or other items in which a child may be placed, and one of skill in the art will recognize that the attachment features of shopping cart liner 800 may be adapted to other kinds of liners as well. Shopping cart liner 800 includes leg holes 801 and a padded shell 802. A rod 803 is embedded in a portion of shopping cart liner 800 that a child faces when the liner is in use. As in other embodiments, rod 803 may be embedded by wrapping it in a fabric sleeve 820 or other sheet sewn into shopping cart liner 800, or may be embedded in some other way. As illustrated in FIG. 8A, fabric sleeve 820 is sewn into a seam 822 of liner 800 such that it forms a tube into which rod 803 may be inserted. After inserting rod 803 into the sleeve, each end 824 of the sleeve is folded back and then sewn onto itself as well as to the liner 800 as illustrated in FIG. 8A. Alternatively, an additional piece of fabric can be sewn over the ends and to the liner to insure that the ends of rod 803 will not poke through the sleeve. A clip 301 is slidingly engaged with rod 803, and toys or other items 804 are attached to shopping car liner using compressible members passed through the hole in clip 301. Typically, slider clip 301 is inserted over rod 803 and sleeve 820 prior to sewing ends 824 back on themselves to insure that clip 301 will remain attached to rod 803. In this example, both items 804 are shaped like flowers, and both are attached through the same opening in clip 301. Shopping cart liner 800 may also have holes 805 through which other items may be attached using the methods described above. When attached to shopping cart liner 800, items 804 provide entertainment and stimulation to a child riding in the shopping cart, and because they are attached, are not likely to be dropped or lost.

FIG. 9 shows a changing pad 900 in accordance with embodiments of the invention. A changing pad is a soft pad of a convenient size and shape for holding an infant while its diaper is changed. Example changing pad 900 includes a cover 901 stretched over the outer surface of pad 900 in a manner similar to a fitted sheet over a mattress. Optionally, a protective liner 902 may be placed on top of cover 901. This may be constructed of a waterproof material to protect pad 900. Changing pad 900 also includes features for attaching items in accordance with the systems and methods described above. For example, one or more rods 904 may be embedded in various seams of cover 901, either at interior seams around opening 903 or at outer edges of changing pad 900. Rods 904 may encompass only a portion of a particular seam, as is shown in FIG. 9, or may encompass all of one or more seam. Rods similar to rods 904 may be embedded in other ways in changing pad 900 as well. Preferably, at least one clip 301 is slidingly engaged with each embedded rod. (Only one clip 301 is shown in FIG. 9 for clarity.) Items such as item 905 may be attached through the holes of any or all of the clips, as described previously.

Changing pad 900 may also include tabs 906 protruding from cover 901 and having holes 907, providing additional or alternative attachment sites. Other kinds of pads, for example play pads, may be used in child care, and one of skill in the art will recognize that attachment features described above in relation to changing pad 900 may be adapted for use in other kinds of pads as well.

In some embodiments, an arch or an arm may be suspended over the changing pad in a manner similar to the play yards, swings and bouncers described herein. This arch or arm may include a flexible semi-rigid rod as in other embodiments to which a slider clip may be attached. In this manner, various items may be suspended over the changing pad. It could also include holes or loops through which the toys described herein may be attached.

The slider clips, rods, tracks, as well as the openings and loops for receiving compressible toys that are described herein may be incorporated into a variety of other products, such as on a crescent shaped pillow, including those described in U.S. Pat. Nos. 5,261,134, 5,661,861; 6,038,720; 6,055,687; 6,685,024; 6,434,770; 6,671,908; 7,017,212; 6,279,185; 6,412,128; 7,451,508; 7,127,760; 6,944,898; 7,587,773; 7,472,443; and 7,404,222, incorporated herein by reference, and on slipcovers, including the slipcovers described in U.S. Pat. No. 6,453,493; U.S. Pat. No. 6,625,828; U.S. Pat. No. 6,851,143; U.S. Pat. No. 7,000,274; and U.S. Pat. No. 7,146,663, incorporated herein by reference. As another example, the attachment systems described herein may be used to attach items such as a pacifier, a pocket (such as to hold a cell phone or bottle), or the like to a large piece of equipment. As further examples, the attachment systems described herein may be used in connection with other equipment such as a walker, a jumper (that hangs in a doorway with elastic straps hooked onto a seat so baby can jump up and down), a pram or stroller, a baby exerciser or rocking saucer (like those sold by Evenflo and ExerSaucer), a baby activity center (such as those similar to the ExerSaucer, but without the saucer-shaped bottom), a toddler chair, a bassinet or crib, a crib mobile (having the slider system and/or holes in the mobile canopy), a crib bumper, a car seat organizer (such as a pocket organizer which fits over the back of the front seat), a storage basket, a storage bin or toy chest, a diaper bag, a baby carrier, including front or back baby carriers, a baby sling, an infant bath tub, a bath tub infant seat or a bath tub accessory with a suction cup, a baby bib, a book for baby (where the slider clip may be incorporated into the spine of the book or across the cover), a rocking chair, a glider chair, or the like.

FIG. 10 illustrates an interior view of example shopping cart liner 800, and illustrates additional features that may be present in some embodiments. Shopping cart liner 800 includes a body 1001 configured to nest in the child seat portion of a shopping cart. Shopping cart liner 800 or a similar liner could also be used in a high chair or similar chair, for example a chair of the kind often provided by restaurants for seating children at table height. The body 1001 may be made of a fabric or other similar material that is flexible and can conform to the shape of the shopping cart while being comfortable and safe for a child seated in shopping cart liner 800. Preferably, body 1001 is made of a washable material. Examples of suitable materials for body 1001 include cotton, nylon, LYCRA, denim, polyester, microfibers, synthetics, and the like. Body 1001 may be padded, for example using a batting or foam, which is also preferably washable. In some embodiments, body 1001 may include two layers of fabric or other flexible material with padding between the layers. For example, a batting or other padding material could be quilted into shopping cart liner 800. A track 1005 is embedded in shopping cart liner 800 and positioned near the handle by which a shopper would push the shopping cart. (The handle is not visible in FIG. 10, but is generally under track 1005 and is covered by shopping cart liner 800.) Track 1005 may be in the form of rod 803 as described above, and may be wrapped in a fabric sleeve 820, which may be sewn into a seam 822 of shopping cart liner 800, or may be embedded in another way. The ends of track 1005 may be captured in the manner described above and shown in FIG. 8A.

In other embodiments, track 1005 may be made of foam, plastic, or rubber welt material. Welt is an elongate flexible material, often circular in cross section, and is available from National Bias Binding Corp. of 140 58^(th) Street 2L, Brooklyn, N.Y. 11220, among other suppliers. One advantage of using foam, plastic, or rubber welt to form track 1005 is that it is machine washable. Being substantially flexible, it may also be configurable into complex curves and other shapes, and may permit the item in which it is embedded to be folded, rolled, or otherwise reduced in size for packing or storage. It may be possible to sew directly across a track made of foam, plastic, or rubber welt, and when a track made of such a welt is embedded in a seam of a product, the ends of the track may be captured by simply turning the track through the seam and sewing across the track. This technique is explained in more detail below.

Openings or leg holes 801 are positioned to enable the feet of a child seated in the shopping cart to protrude through the body 1001 when the child is seated in the lined seat portion of the shopping cart.

A clip 1004 is slidingly engaged with track 1005. Clip 1004 defines an opening for attaching an item to the shopping cart liner. Clip 1004 may be similar, for example, to clip 301 or clip 350 shown in FIGS. 3B and 3C. Any suitable item may be attached to the shopping cart liner via clip 1004, for example, a toy, teething ring, doll, pacifier, or other item may be attached, by the methods described above. While only one clip 1004 is illustrated, it is to be understood that multiple similar clips could be engaged with track 1005. One or more holes 805 may be provided in body 1001 for attaching other items to shopping cart liner 800. Holes 805 may be formed, for example, similar to buttonholes, with dense stitching around the perimeter of the hole to lend strength and durability.

Shopping cart liner 800 may also comprise a seat belt 1002 affixed to body 1001 or another part of shopping cart liner 800, for securing a child to shopping cart liner 800. Seat belt 1002 may include a fastener 1003, which may be a buckle, snap feature, or other kind of suitable fastener. Fastener 1003 may be selected to be secure when fastened but still relatively easily disengaged by an adult. Seat belt 1002 may be fixed to shopping cart liner 800, for example by stitching. Preferably, though, seat belt 1002 is not fixed to shopping cart liner 800, but threads through openings in the liner such that one or both ends of seat belt 1002 can be threaded through or around bars or other features of the shopping cart and then the ends of seat belt 1002 connected, to secure both shopping cart liner 800 and the child to the shopping cart. In another embodiment, shopping cart liner 800 may not include a seat belt 1002, but may include openings positioned so that an existing safety strap that is part of the shopping cart could be threaded through the liner openings and around the child.

FIG. 11 shows a rear view of shopping cart liner 800 in use. A rear flap 1101 may hang down from the back of the seat portion of the shopping cart, and may include other features for the convenience of the user. For example, one or more pockets 1102 may be sewn into rear flap 1101 for holding items that a caregiver may wish to keep readily accessible, for example a baby bottle, cellular telephone, or other item. A pocket such as pocket 1102 may include an elastic rim 1103, for holding items more securely. A specialized pocket 1104 may be specially constructed to hold a package or dispenser 1105 holding tissues or wipes, leaving the package or dispenser 1105 partially exposed so that tissues or wipes can be dispensed easily. For example, pocket 1104 may be made of a set of partially-overlapping fabric flaps that constrain the edges of package or dispenser 1105 while leaving the center of package or dispenser exposed. One or more flaps similar to rear flap 1101 may be provided at the front of shopping cart liner 800, or on either or both sides of the shopping cart liner 800, and may include pockets or other features of convenience to the user.

FIG. 12 shows an interior view of shopping cart liner 800, used in combination with a pillow 1201. Pillow 1201 may be generally arc shaped, including two curved arms 1202 extending from a midsection 1203, to define an open well 1204 to receive a child. Pillow 1201 may be between about 12 and about 20 inches wide, and is preferably about 16 inches wide. Open well 1204 may be between about 5 and 8 inches across, and is preferably about 6 inches across.

Pillow 1201 may be especially suitable for using shopping cart liner 800 with a very small child, such as an infant. Pillow 1201 may be placed in the lined seat portion of the shopping cart prior to or after seating the child. Once pillow 1201 and the child are in place, pillow 1201 may fit around the child's waist to support the child in an upright seated position. Pillow 1201 may be a small version of a pillow such as is described in one or more of U.S. Pat. Nos. 5,261,134, 5,661,861;

6,038,720; 6,055,687; 6,685,024; 6,434,770; 6,671,908; 7,017,212; 6,279,185; 6,412,128; 7,451,508; 7,127,760; 6,944,898; 7,587,773; 7,472,443; and 7,404,222, previously incorporated by reference.

Features may be provided on pillow 1201, shopping cart liner 800, or both for securing pillow 1201 to shopping cart liner 800. For example, pillow 1201 may include a fabric loop sewn or otherwise formed in the back of midsection 1203, and shopping cart liner 800 may include a tie sewn or otherwise formed near the bottom and back of the seating area of shopping cart liner 800. Such a tie could be made of a fabric or other material similar to the material the shell of shopping cart liner 800 is made of. The tie could be threaded through the loop and tied to hold pillow 1201 in place, and can easily be undone to allow pillow 1201 to be removed. The positions of the loop and tie could also be reversed, with the loop being part of shopping cart liner 800 and the tie being part of pillow 1201. Other kinds of connections are also possible. For example, a loop, tab, or other feature including the “hook” portion of a hook and loop fastener may be fixed to either pillow 1201 or shopping cart liner 800, and a feature including the “loop” portion of the fastener fixed to the other, so that pillow 1201 could be attached to shopping cart liner 800 by engaging the hook portion and the loop portion.

In some embodiments, shopping cart liner 800 may be used or provided in combination or conjunction with other accessories useful to a user of shopping cart liner 800. For example, a shopper who is caring for a child seated in shopping cart liner 800 may wish to carry items to attach to shopping cart liner 800, as well as other items such as diapers, clothing for the child, or other items useful during a trip to a store. Accordingly, shopping cart liner 800 could be paired with a tote bag or other accessory. A shoulder bag or other tote may conveniently be made of materials similar to body 1001 of shopping cart liner 800, and may form a matching companion piece to shopping cart liner 800. Such a bag may also provide a convenient way to carry pillow 1201.

FIGS. 13-15 illustrate additional details of how a track may be attached to a piece of child care equipment, for example shopping cart liner 800.

FIG. 13A shows one way of attaching a track at a seam in a piece of child care equipment having a shell with two layers 1301 a and 1301 b. In this view, a rod or welt 1302 is shown in cross section, and serves as a track. For example, welt 1302 may be made of extruded, foam, plastic, or rubber. Rod or welt 1302 is wrapped in a sleeve 1303, shown in dashed lines. As is described above, sleeve 1303 may be made of a material having good durability and strength, for example nylon or another suitable material. Preferably, sleeve 1303 is sewn along stitching line 1304 to snugly capture rod or welt 1302 within sleeve 1303, leaving two layers of sleeve 1303 protruding to form a tab 1305.

In this example, the shell is made in two layers 1301 a and 1301 b, with a padding or fill material 1306 between them. During construction, the edges of layers 1301 a and 1301 b may be generally aligned with the edge of tab 1305, and the four thicknesses of materials (layers 1301 a and 1301 b, and two thicknesses of sleeve 1303) sewn together along stitching line 1307. It may be convenient to make the attachment of sleeve 1303 to the shell with the shell “inside out”. Once the shell is nearly complete, it may be turned “outside out” and filled with padding or fill material 1306. In this way, any edges of layers 1301 a and 1301 b and sleeve 1303 that might be subject to fraying are inside the finished product. A clip 350 or other clip according to embodiments of the invention may be engaged with rod or welt 1302, and the ends of sleeve 1303 addressed to capture rod 1302 longitudinally. Alternatively, rather than sewing sleeve 1303 and layers 1301 a and 1301 b together in a single operation, rod or welt 1302 wrapped in sleeve 1303 may be sewn to either layer 1301 a or 1301 b in one operation, and then to the other layer in a later operation, so that there may be three stitching lines at a particular seam.

Rod or welt 1302 is preferably spaced from the body of the child care equipment by a distance D that is sufficient to enable clip 350 to slide freely without catching on layer 1301 a or layer 1301 b. For example, spacing D may be about 1/16 inch to about ¼ inch, or more preferably about ⅛ inch to about 3/16 inch.

FIGS. 13B and 13C show another way of attaching a track to a piece of child care equipment, in accordance with other embodiments of the invention. The technique of FIGS. 13B and 13C may be especially useful for construction of items that are generally flat but include padding, for example play pads, liners for shopping carts or strollers, or other similar items.

In FIG. 13B, a rod or welt 1302 has been previously wrapped in sleeve 1303 and sleeve 1303 sewn along stitching line 1304 to capture rod or welt 1302. Shell layers 1301 a and 1301 b are then stacked together with tab 1305 of sleeve 1303. In addition, a layer of sheet batting or other padding 1308 is also stacked together with tab 1305 and shell layers 1301 a and 1301 b. In this configuration, the sides of layers 1301 a and 1301 b that will form the outside of the product are facing each other. The combined shell layers 1301 a and 1301 b, tab 1305 of sleeve 1303, and padding 1308 are stitched together along stitching line 1309, which may extend along a portion or nearly all of the perimeter of the product. The stitching operation is preferably done with the product “inside out”, and a small portion of the perimeter of the product is left unsewn, to allow for turning the product “outside out”.

FIG. 13C shows the arrangement of layers once the product is turned “outside out” and a clip 350 is attached. The small previously unsewn portion of the product perimeter may then be finished with outside stitching or other finishing. A clip such as clip 350 is assembled onto the track at any suitable stage of the process, but preferably before the ends of the track are fully finished.

FIG. 14 shows one way of attaching a track at an edge of a piece of child care equipment having a single layer of material 1401. In this view, a rod or welt 1402 is shown in cross section, and serves as a track. Rod or welt 1402 is wrapped in a sleeve 1403, shown in dashed lines. Preferably, sleeve 1403 is sewn along stitching line 1404 to snugly capture rod or welt 1402 within sleeve 1403, leaving two layers of sleeve 1403 protruding to form a tab 1405. Each of the two layers of tab 1405 may then be folded under, and the single layer of material 1401 inserted between them, and the five resulting layers of material sewn together along stitching line 1406. In this way, any edges of material 1401 or sleeve 1403 that might be subject to fraying are captured and hidden within tab 1405, between stitching lines 1404 and 1406. Alternatively, sleeve 1403 could be made of a self-edged material, and material 1401 simply sewn between the two thicknesses of tab 1405, leaving the edges of sleeve 1403 exposed. A clip 301 or other clip according to embodiments of the invention may be engaged with rod or welt 1402, and the ends of sleeve 1403 addressed to capture rod or welt 1402 longitudinally. It will be recognized that this technique could also be used to attach a track at an edge of a piece of child care equipment having multiple layers capable of being captured within tab 1405.

FIG. 15 shows another way of attaching a track to a piece of child care equipment having a shell with two layers 1501 a and 1501 b. In this view, a welt 1502 is shown in cross section, and serves as the track. Welt 1502 is extruded, for example of foam, plastic, or rubber, to include an integrally formed flange 1503. Flange 1503 may be used to attach welt 1502 to layers 1501 a and 1501 b by sewing flange 1503 into the seam between layers 1501 a and 1501 b. The sewing may be done simultaneously, such as along stitching line 1504 capturing layers 1501 a and 1501 b and flange 1503 in a single pass, or flange 1503 may be sewn to the layers one at a time. Flange 1503 enables welt 1502 to be attached without being wrapped in a sleeve. The main portion of welt 1502 (to which flange 1503 is connected), could be hollow, for example forming a tube with an opening along its length, or may be fully formed of the welt material, without any hollow portion. It will be recognized that welt 1502 having flange 1503 could also be attached to a single layer shell, or to a multiple-layer shell with both layers on the same side of flange 1503. Many other configurations are possible. Welt 1502 having a flange 1503 may replace a sleeve-wrapped welt or rod in any suitable application, for example the applications shown in any of the Figures.

FIGS. 16A and 16B show a way of capturing the ends of a piece of welt in a seam between two fabric or other flexible layers 1601 a and 1601 b. FIG. 16A shows the assembly from the finished side of the seam, such as the outside of a product, and FIG. 16B shows the assembly from the unfinished side of the seam, such as would be found on the inside of a product. Layers 1601 a and 1601 b are joined along seam 1602. For much of the seam visible in FIGS. 16A and 16B, a track 1603 is sewn into seam 1602, for example by wrapping a piece of welt in a fabric sleeve 1607 and sewing the sleeve into seam 1602 as described above. At a point where it is desired that track 1603 ends, track 1603 is turned inward, so that end 1604 of track 1603 will reside inside the finished product. Stitching 1605 is simply continued across track 1603 to capture track 1603 securely in seam 1602. The point at which track 1603 is turned inward also provides a stop that prevents clip such as clip 350 from sliding past that point or from coming off of track 1603. If desired, multiple stitching passes 1606 may be made over track 1603 to lend strength to the connection.
